Net Promoter Score Categories

Before starting off, let’s first explore the categories of respondents pertaining to Net Promoter Score.

Promoters: The respondents who have scored you a 9 or 10 comes under the category of promoters. They are very much happy with your brand and can help promote it through positive word of mouth.

Passives: The customers who have answered a 7 or 8 are considered passives. They hold a neutral stand. They aren’t really happy with your product nor are they disappointed but you can’t expect them to be loyal to your brand. A better product can lure them towards your competitors.

Detractors: Customers falling under the category of detractors will have scored you in the range of 0-6. This group of customers are extremely unhappy with your brand and you are at the risk of losing them to the competition.

The formula for Calculating NPS

Basically, the following steps are approached during net promoter score calculation.

  • Find the total number of respondents.
  • Find the percentage of Promoters – Divide the number of promoters by the total number of respondents and then multiply by 100.
  • Find the percentage of Detractors – Apply the same step mentioned above with numbers pertaining to the detractors.
  • So, the formula for NPS = % Promoters – % Detractors

Designing a Net Promoter Score Calculator in Excel

Now that we know the categories and formula, let’s explore the method to calculate NPS in excel.
The COUNTIF function is by far one of the easiest and effective ways to calculate NPS in excel. Essentially, the function delivers the count of cells meeting a certain clause or criteria given by you. Here, we will be using the COUNTIF function to segregate and find the number of respondents belonging to each of the categories being, Promoters, Detractors and Passives.

  • Export the data from your NPS survey into a .CSV or .XLS file.
  • Now copy the data from the respective file and paste it into an excel sheet.
  • When that much is done, you will have to find the count of responses in each category. Let’s assume the scores given by respondents are contained in Column B. So, the function for finding the number of responses for:
    • Promoters: COUNTIF (B: B,”>=9”)
    • Detractors: COUNTIF (B: B,”<=6”)
    • Passives: COUNTIF (B: B,”=7”) + COUNTIF (B: B,”=8”)

You can feed in the function to any of the cells, but here’s a warning; do not paste the function into the same column that contains the scores to your NPS survey (in this case column B).

  • Since you have received the total number of respondents in each category, you can find the percentage of each category and then apply the NPS formula in excel i.e % promoters – % detractors.
  • If the data set is quite large, then you may want to use a simpler method to calculate NPS in excel. Here’s a single excel formula to find your net promoter score:

ROUNDUP((100*((COUNTIF(B:B,”>8″)-COUNTIF(B:B,”<7″))/COUNT(B:B))),0)

As I mentioned before, you can paste this formula in any cell of your excel sheet except in the column that contains your NPS responses. Use the formula and you can calculate and find your overall net promoter score in excel in a jiffy! Indeed a DIY Net Promoter Score calculator in excel!
